While many hotels, cafes, and some public spaces in Prague offer free Wi-Fi, its reliability and security can vary. For consistent, secure connectivity while navigating the city, using ride-sharing apps, or staying connected in areas like Charles Bridge or Žižkov, a personal eSIM data plan is far more dependable than relying solely on public Wi-Fi.
